March 22, 2007 -- SOME celebrities don't know when to keep their
traps shut - like Charlie Sheen and Rosie O'Donnell, who are throwing
their weight behind the twisted theory that the United States government
was behind the 9/11 terror attacks.

Page Six has learned that Sheen, the hooker-loving Hollywood hunk,
has agreed to narrate a new version of the loopy YouTube documentary
"Loose Change," which claims that a corrupt faction within
the federal government orchestrated the mass murder at the World
Trade Center.

Sources say Sheen - whose father, Martin Sheen, has been arrested
63 times protesting on behalf of various leftist causes - is in
talks with Dallas Mavericks owner Mark Cuban's Magnolia Pictures
to distribute "Loose Change." Sheen has called for a new
independent probe of the attack, telling Alex Jones' radio show:
"It seems to me like 19 amateurs with box cutters taking over
four commercial airliners and hitting 75 percent of their targets,
that feels like a conspiracy theory. It raises a lot of questions."

Sheen's rep confirmed his participation. Cuban e-mailed us: "We
are having discussions about distributing the existing video with
Charlie's involvement as a narrator, not in making a new feature.
We are also looking for productions with an opposing viewpoint.
We like controversial subjects, but we are agnostic to which side
the controversy comes from."

Meanwhile, on her blog, O'Donnell has pasted in a widely debunked
rundown of the collapse of 7 World Trade Center from the whatreallyhappened.com
Web site, created by conspiracy theorist Matt Rivero.

O'Donnell repeats his discredited theories, which include the notion
that because the fires were not evenly distributed, it made the
building's perfect collapse into its footprint "impossible
that landlord Larry Silverstein told the FDNY that "the smartest
thing to do is pull it," a phrase conspiracy theorists take
to mean that he ordered the skyscraper's destruction; and that firefighters
withdrawing from the building feared it was going to "blow
up."
